Hey, Mark. I hope I'm not misunderstanding, but importing models from
one app to another is no problem.
For example, assume Django project is called 'project' and you have
two apps named 'people' and another named 'tagging'.
In your people/models.py:
from django.db import models
from project.tagging.models import Tag
class Person(models.Model):
name = models.CharField(maxlength=100)
tag = models.ManyToManyField(Tag)
With that said, certainly play around with this to learn, but I would
also recommend checking out django-tagging (http://code.google.com/p/
django-tagging/) for an awesome tagging app.
